Description

BACKGROUND OF THE INVENTION

The present invention is directed to a new and distinct variety of chrysanthemum botanically classified as Dendranthema grandiflora. The varietal denomination of the new chrysanthemum is `GOLD CREST`.

The female parent of the new variety is the variety known as `Lynn` (U.S. Plant Pat. No. 8,171) and the male parent is the variety known as `Empire Serenade` (U.S. Plant Pat. No. 8,803). The new variety has been asexually reproduced by vegetative cuttings in Ventura County, Calif. and the distinguishing characteristics are retained through successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

`GOLD CREST` produces large, yellow decorative flowers.

COMPARISON WITH PARENTS

`GOLD CREST` differs from the female and male parents in having yellow flowers whereas `Lynn` produces pink flowers and `Empire Serenade` produces coral pink flowers.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph shows a typical specimen of the plant and flowers of the new variety with colors being as nearly true as possible with illustrations of this type.

DESCRIPTION OF THE PLANT

The following description of the new variety is of specimens grown in a greenhouse in Ventura County, Calif. in the month of April. `GOLD CREST` has not been observed under all possible environmental conditions. The phenotype may vary with variations in the environment such as temperature, light intensity, day length and cultural conditions. The color designations herein are from The Royal Horticultural Society Colour Chart except where general terms are used.

To produce a commercial product the plants may be pinched once about ten days after planting. It has been observed that longevity of individual blooms of `GOLD CREST` is about 22 days and the response time is about 7 weeks. No growth retardant has been used on specimens described. Useful growing conditions include night temperatures of about 62.degree.-64.degree. F. and day temperatures of about 70.degree.-75.degree. F. Natural season response in Ventura County, Calif. is early September.
